BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofChrysanthemum plant, botanically known as Chrysanthemum X morifolium andhereinafter referred to by the name ‘G20ARL11OR’.

The new Chrysanthemum plant is a product of a planned breeding programconducted by the Inventor in Oostnieuwkerke, Belgium. The objective ofthe breeding program is to create new uniformly mounding and freelyflowering Chrysanthemum plants with unique and attractive ray floretcoloration.

The new Chrysanthemum plant is a naturally-occurring whole plantmutation of Chrysanthemum X morifolium ‘Arluno Pink’, not patented. Thenew Chrysanthemum plant was discovered and selected by the Inventor as asingle plant from within a population of plants of ‘Arluno Pink’ in acontrolled greenhouse environment in Oostnieuwkerke, Belgium in October,2015.

Asexual reproduction of the new Chrysanthemum plant by vegetativeterminal cuttings was first conducted in a controlled greenhouseenvironment in Oostnieuwkerke, Belgium in January, 2016. Asexualreproduction by vegetative terminal cuttings has shown that the uniquefeatures of this new Chrysanthemum plant are stable and reproduced trueto type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘G20ARL11OR’. These characteristics incombination distinguish ‘G20ARL11OR’ as a new and distinct Chrysanthemumplant:

-   -   1. Upright, outwardly spreading and uniformly rounded plant        habit; moderately vigorous growth habit.    -   2. Freely branching habit; dense and full plant habit.    -   3. Dark green-colored leaves.    -   4. Uniform and freely flowering habit.    -   5. Long flowering period.    -   6. Decorative-type inflorescences with ray florets that are        greyed red in color.

Plants of the new Chrysanthemum can be compared to plants of themutation parent, ‘Arluno Pink’. Plants of the new Chrysanthemum differprimarily from plants of ‘Arluno Pink’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum are more uniform than plants        of ‘Arluno Pink’.    -   2. Ray florets of plants of the new Chrysanthemum are greyed red        in color whereas ray florets of plants of ‘Arluno Pink’ are        light red purple in color.

Plants of the new Chrysanthemum can be compared to plants of theChrysanthemum X morifolium ‘Arluno Dark Pink’, disclosed in U.S. Plantpatent application Ser. No. 15/732,901. In side-by-side comparisons,plants of the new Chrysanthemum differ primarily from plants of ‘ArlunoDark Pink’ in ray floret color as ray florets of plants of the newChrysanthemum are greyed red in color whereas ray florets of plants of‘Arluno Dark Pink’ are light red purple in color.

Plants of the new Chrysanthemum can be compared to plants of theChrysanthemum X morifolium ‘GED18ARL2Y’, disclosed in U.S. Plant patentapplication Ser. No. 15/732,906. In side-by-side comparisons, plants ofthe new Chrysanthemum differ primarily from plants of ‘GED18ARL2Y’ inray floret color as ray florets of plants of the new Chrysanthemum aregreyed red in color whereas ray florets of plants of ‘GED18ARL2Y’ arebright yellow in color.

Plants of the new Chrysanthemum can be compared to plants of theChrysanthemum X morifolium ‘GED18ARL6V’, disclosed in U.S. Plant patentapplication Ser. No. 15/732,907 In side-by-side comparisons, plants ofthe new Chrysanthem differ primarily from plants of ‘GED18ARL6V’ in rayfloret color as ray florets of plants of the new Chrysanthemum aregreyed red in color whereas ray florets of plants of ‘GED18ARL6V’ aredark red purple in color.

Plants of the new Chrysanthemum can also be compared to plants ofChrysanthemum X morifolium ‘Amiko Bronze’, disclosed in U.S. Plant Pat.No. 34,201 In side by side comparisons, plants of the new Chrysanthemumdiffer primarily from plants of ‘Amiko Bronze’ in the followingcharacteristics:

-   -   1. Plants of the new Chrysanthemum are more uniformly rounded        than plants of ‘Amiko Bronze’.    -   2. Leaves of plants of the new Chrysanthemum are darker green in        color than leaves of plants of ‘Amiko Bronze’.    -   3. Plants of the new Chrysanthemum flower about one week later        than plants of ‘Amiko Bronze’.    -   4. Plants of the new Chrysanthemum have slightly smaller        inflorescences than plants, of ‘Amiko Bronze’.    -   5. Ray florets of plants of the new Chrysanthemum are greyed red        in color whereas ray florets of plants of ‘Amiko Bronze’ are        greyed orange in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of thenew Chrysanthemum plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. The photographcomprises a side perspective view of a typical flowering plant of‘G20ARL11OR’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations andmeasurements describe plants grown in 19-cm containers in an outdoornursery in Oostnieuwkerke, Belgium during the summer and autumn andunder cultural practices generally used in commercial Chrysanthemumproduction. During the production of the plants, day temperatures rangedfrom 20° C. to 25° C. and night temperatures ranged from 12° C. to 18°C. Plants were 20 weeks old when the photograph and detailed descriptionwere taken. In the following description, color references are made toThe Royal Horticultural Society Colour Chart, 2005 Edition, except wheregeneral terms of ordinary dictionary significance are used.
